SUPPORTING BASE FOR STOOLS Filed Oct. 50, 1929 Patented Oct. 20, 1931UNITED STATES PATENT OFFICE rnnononn BINK, F PORT WASHINGTON, WISCONSIN,ASSIGNOR TO GILSON-BOLENS MANUFACTURING COMPANY, OF PORT WASHINGTON,WISCONSIN SUPPORTING- BASEIOR STOOLS Application filed October 30, 1929.Serial No. 403,440.

'lnis invention relates to improvements in support-bases for stools.

One of the objects of my invention is the provision of a support forstools and seats which are especially adapted for use in connection withlunch counters and the like, where r the seat is arranged comparativelyclose the counter and is rotatably mounted, so that when the party usingthe seat desires to leave the counter they will swingaround in the seatand the seat is so mounted that it will readily return to its normalposition, facing the counter.

Another object of my invention is the provision of a novel structurewherein a portion thereof is manufactured as a separable part of asupporting standard and adapted to be used in connection with well knownsupporting standards on the market at the present time and the seatsupporting frame is provided with means to cooperate with the separatepart in order to normally maintain the seat in position, facing thecounter or table.

A further object of the invention is the provision of a bearing sleevewhich is adapted to be forced in the upper end of a hollow base standardand provided w1th an niclined face adapted to cooperate with thecomplementary fa e on the seat supporting element, whereby 8? when theseat supporting element is rotated in one direction, the complementaryfaces will cooperate for returning the seat supporting element to itsnormal position whereby the seat carried thereby can always be main- 53'tained in one position when in use, and this position is preferablyfacing the table or counter adjacent the seat.

With the above and other objects in view, the invention consists in thenovel features of construction, the combination and arrangeportingmember constructed in accordance with my invention, with parts thereofbroken away and illustrated in cross section, and the member in itsnormal position;

Figure 3 is a plan view of a seat supporting element;

Figure 4 is a top plan view with the seat support removed;

Figure 5 is a side elevation of the seat support; and,

Figure 6 is a detail vertical sectional view ofthe upper end of thestandard showing the bearing sleeve in position.

In carrying out my invention, it is one of the principal objects of myinvention to provide asupporting element for counters or table seatswhichcan be used in conjunction with a hollow base standard and can bemanufactured as a separate part or manufactured and placed on the marketwith'the hollow base standard.

Referring to the drawings, it will be noted that I have illustrated asubstantially hollow base: standard 1, having a securing flange 2 at itslower end whereby screws or the like can be used for connecting thestandard to the floor. The upper end of the standard is formed with anoutwardlyprojecting flange 3 and this standard is preferably hollowthroughout its length and tapers inwardly toward its upper end so thatthe upper end thereof is considerably smaller than the base orsupporting end.

In the construction of a stool or seat support, I provide a bearingsleeve 4 having an outwardly projecting portion 5 at one end and thissleeve is preferably forced into the up 361 small end of the standard 1,as shown in Figures 1 and 6 of the drawings. The sleeve 4 is ofsuflicient size to warrant a tight fit or what is known as a driving fitso that the sleeve will not be displaced afterbeing driven into theupper end of the standard, and the flange 5 will form a stop for thesleeve to limit its movement as it cooperates with the flange 3, asshown in Figures 1 and 6.

The seatsupport element which is removably mounted upon the standard 1comprises a centrally disposed cylindrical body 6 and projecting fromthe central portion of this body is a stud 7 which is adapted to beposi- The body 6 has its lower face inclined, as shown at 8 to cooperatewith the inclined face 9 on the upper end of the sleeve 4 so that whenthe parts are in their operative position, as shown in Figure 1, thestud 7 will be rotatably mounted in the sleeve 4 and the complementaryfaces 8 and 9 will be arranged in sud: position that the highest pointof the face 8 is disposed at the lowest point of the face 9.

Extending radially from the body 6 are a plurality of seat supportingarms 10, the outer ends of which are formed with aperturecl ears 11which are connected by means of screws 12 to the seat 13. The seat inthis instance may be provided with a back portion 14 0t any suitabledesign.

It will be apparent that when the seat is in its normal position, asshown in Figure 1, the high point of the inclined face 8 is preferablydisposed within the upper end of the base standard 1 so to assist thestud 7 in maintaining the seat 13 in operative position when a person issitting thereon. However, when the seat 13 is rotated to allow theperson sitting thereon to remove himself from the seat, the high pointof the inclined face 8 will ride up toward the highe t point of theinclined face 9. and as the outer circumference of the lower portion ofthe body 6 is rounded, the high point will readily travel to itsnormalposition after the weight has been relioved fromthe seat, theweight of the seat itself returning the complementary faces 8 and 9 totheir normal positions. I Fromthis, it will be apparent that the seat Hiwill at all times be normally facing the mmtar'or table and be ready foroccupancy by simply rotating the seat slightly to allow a person to sitdown beside thetable or countor, the weight of the person readily movingthe seat to a position facing thecounter or table.

It is most essential that I call attention to the fact that the mainparts of this inven time are the bearing sleeve 4, and the seatsupporting element to which the seat 13 is attached. each of thesemembers being cast in asi'ngle part so that the main parts of thesupporting member are formed of two singlb pieces. and while the ba sestandard 1 has been used heretofore, it will be readily apparent thatthesleeve 4 can be used in conneotion withthe well known hollow supportinstandard.

While haveshown and described the pre fhm'edembodiment of my invention,it will be apparent that slight changes may be made in the constructionwhen putting the invention into practice without departing from thespininoftiie same or the scope of the appended claims.

1; In combination with a hollow base standard having an outturned flangeat its upper end, a bearing sleeve fitted into the up per end of thestandard, a flange on the sleeve to limit the movement of the sleeve inthe standard, an inclined bearing face upon the outer end of the sleevewith its lowest point below the upper end of the standard, a seatsupport including a cylindrical body having an imlined belrmgl' facecooperating with the bearing face on t e sleeve with its highest pointnormall positioned within the standard and a stu projecting from the clindrical body and extending into the earing sleeve.

2. In combination with a hollow base standard, a bearing sleeve fittedinto the upper end of the standard, means for limiting the inwardmovement of the sleeve relative to the standard, an inclined bearingface upon the outer end of the sleeve with its lowest point below theupper end of the standard, a seat support including a cylindrical bodyhaving an inclined beanng face cooperating with the bearing face on thesleeve and having its highest oint inwardly positioned within the stanard and a stud projecting firomthe cylindrical body and extending intothe bearing sleeve.

In. testimony that I claim the foregoing I have hereunto set my hand atPort Washington, in the county of Ozaukee and State of Wisconsin.
